City power distribution network superconducting cable application scheme comparison and selection method based on analytic hierarchy process

Abstract

The invention discloses a city power distribution network superconducting cable application scheme comparison and selection method based on an analytic hierarchy process. The method comprises the following steps: firstly, classifying, investigating and collecting investment cost, power supply resource requirements and benefit factors involved in a superconducting cable scheme, and performing modeling calculation; secondly, carrying out normalization processing on the comprehensive evaluation result of the non-quantizable factors; thirdly, calculating a comprehensive evaluation result corresponding to the scheme through result multiplication and accumulation according to different factors and indexes subjected to corresponding weight normalization, and taking the scheme with the maximum result as a comparison and selection recommendation scheme; establishing a scheme evaluation element judgment matrix; checking the consistency of the scheme evaluation element judgment matrix, and determining an evaluation weight; and finally, solving a characteristic equation about the scheme evaluation element judgment matrix to obtain each factor corresponding to the maximum characteristic value lambda max and a corresponding weight. According to the superconducting cable planning scheme comparison and selection model for quantifying multiple factors of cost and benefit, the defects of existing subjective evaluation are overcome.

Description

Technical field [0001] The present invention relates to the field of computer-aided technology with network planning, in particular, to the city selected based on analytic hierarchy process applications with superconducting cable grid ratio. Background technique [0002] The superconducting cable has a low loss, large transmission capacity, to save material and low pollution characteristics. Superconducting cables achieve lower voltage levels comparable with traditional cable transmission capacity required, and thus has a broad application prospects in high load density, high load demand, high network losses, land and channel resources scarce urban grid. With the superconducting cable in the superconducting tapes, manufacturing processes, systems design and construction of the results continue to accumulate, superconducting cables have the basic technical conditions applied in practical engineering. [0003] Superconducting cable is limited to strip capacity is low, still need to...

Problems solved by technology

[0005] However, in practical applications, there is a lack of comparison and selection methods that consider various influencing factors and meet the needs of superconducting cable applications.

The lack of reasonable and scientific comparison and selection methods can easily lead to insufficient comprehensive considerations in superconducting cable planning and later implementation, lack of reasonable quantitative basis, low utilization rate of superconducting cables after production, and inability to give full play to their large capacity and low loss. Significant advantages, thus reducing investment benefits, is not conducive to the subsequent promotion and popularization of superconducting cable engineering
